In a world where shadows have been separated from their owners and have developed personalities of their own, players assume the role of a shadow-detector, tasked with solving mysteries involving bizarre crimes committed by rogue shadows. Each case reveals twisted secrets and surreal interactions with objects animated by their own shadow's humor, obscured motives, and unpredictable behavior. Players must navigate through vivid, shadowy environments, gather clues, interrogate both humans and their rebellious shadows, and put the pieces together before time runs out.
